BOX-OPENING DEVICE.

Specification of Letters Patent. Patented Mar, 16, 1920.

Application filed ma 29, 1919. Serial No. 300,512.

To all whom it may concern:

Be it known that I, GLEN S. HuMPHREx,

a citizen of the United States, and a resident of the city of New York,borough of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved Box-@pcuing Device, of which the followingis a full, clear, and exact description.

This invention relates generally to a new and improved airtight box, andmore specifically to a means therefor by which the parts may beseparated.

It is'not broadly new to provide ameans for conveniently removing acover from the body of a box, but in constructions heretofore used ithas necessitated the repositioning of the removing means in order toafford a free path for replacing the ,cover on the body of the box. A

One of the'objects of this invention is to. provide a construction whichwill overcome the above objection.

A further object of this invention is to provide in an airtight box asimple and inexpensive means whereby the cover, may be readily separatedfrom the body of a box without necessitating the use of any hinged ormoving pivoted arts or the use of any prying means there or. L

A urther object of this invention is to provide in a box a means forremoving a coverfrom the body, which may be readily applied to theordinary airtight box having a bead on one of the members.

Still a further object of this invention is to provide in an airtightbox a construction by which the parts may be given a relativelongitudinal movement by pressing laterally against a resilient membercarried by one of the parts. Y

Still a further object of this invention is to provide a device forremoving the cover of a boxiwhich, after the cover-has been separated,automatically springs back to a position which facilitates theapplication of the cover to the body of the box.

, The above objects are accomplished by providing a'resilient membercarried by one member of the box and engaging a bead or,

projection on the other member of the box, the resilient member being soformed and arranged that by the application 'of a latrelativelongitudinal movement of" the cover and body is ob? tained, after whichthe resilient member immediately assumes its original form and position.

@ther objects and advantages will be apparent from the followingdescription and accompanying drawings in which similar in the severalviews.

Figure 1 is an elevation view of a box with the invention appliedthereto.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a view showinga modification of the invention.

In Figs. 1 and 2 of the drawings showing a preferred form of theinvention, an airtight box is shown comprising a cover 1 and a body 2,the cover having a circular disk-like top 3 and a downwardly etxendingside 4 extending therearound. The cover 1 is preferably made of onepiece of stamped sheet metal and is formed with a rounded corner at theupper edge of the side 4. The body 2 is also preferably made of onepiece of stamped sheet metal and comprises a raised bottom 5, an annularflange or bead 6 extending therearound, and the upwardly upper edge 8thereof preferably turned inward to facilitate the positioning of theside 40f the cover 1 thereover.

Another outwardly-turned head 9, is formed around the bod .Zin the side7 beextending side 7 having the.

characters of reference designate like parts low the upper edge t ereof,said bead 9 functioning as a stop to position the lower edge 10 of theside 4 of the cover 1. The bead 6 projects out from the side 7 of thebody 2.

As a means of obtaining a relative longitudinal movement of the cover 1and body 2 to separate them, there is provided a re silient member 12,one end of which is secured preferably to the side 4 of the cover 1 by asuitable rivet connection 13 or other means, there being provided raisedbeads 14 adjacent the end of the member 12, to hold it against turningpoint, the other end 13 of said member 12 engaging the head 6 of thebody 1, and the part intermediate of the ends of the resilient member 12being spaced from the side 7 a sufficient distance so that when a forceis applied thereto, there will be a tendency to straighten said member12, thus separat ing the cover relative tween.

longltudinal movement therebeland the body 2 by causing a when securedat only one arated the resilient member 12 will resume again applied tothe body 2, there will be no its original form so that when the cover isprojecting parts obstructing the path of the and scope of thisinvention.

Having thus described the invention, what I claim as new is:

1. In a box, comprising a cover and body portions having a bead thereon,a member having one end thereof secured to the side of one .of saidparts, the other end thereof being normally in engagement with saidbead, said member having aportion thereof spaced from the side of thebox so that when a force is applied thereto, the relative longitudinalmovement of the. cover and body portions will be obtained.

' carried by ing 2. In a box, comprising a cover and a body portionhaving a bead thereon, a means the cover of the box forseparatbox, saidmeans including a resilient member having one end thereof fixed 0n theside of the cover and held against rotation the cover from the bodyportion of the said means including a resilient member having one endthereof secured to the side of the cover and a means to prevent rotationof said member thereon, the other end of said member being normally inengagement with said projection, said member being normally spaced fromthe box between the point of engagement with said projection and thepoint of connection with the cover so that if a pressure is applied tosaid member, said member will tend to straighten and cause theseparation of one side of the cover and the body of the box.

4. In a box, comprising a cover and a body portion, a means carried bysaid cover and held against rotation thereon for separating one side ofsaid cover and body portion of the box, said means including a resilientmember having one end thereof ecured to the side of the cover and theother end thereof in engagement with a projection on said body portion,a portion of said resilient member being normally spaced from the box sothat as a pressure is applied thereto, the cover and body of the boxWill be separated, the said resilient member being so formed that afterthe cover and body have been separated, said resilient member willassume its previous form and will ofier no obstructionwhen the cover isagain applied to the body of the box.

5. In a box, comprising a cover and a body having a bead thereon, a bentspring member having one end thereof fixed on the side of the cover andheld against rotation there on, the other end of said member normallyengaging the head of said body portion.

6. In a box, comprising a 'bod part and a cover therefor, a resilientmem er having one end thereof secured to the side. of the cover and theother end thereof being normally in engagement with the bead, said resilient member being bent intermediate the ends thereof so that if apressure is applied thereto, one side of the cover and body will beseparated, after which the resilient member will assume its previousbent form.
